7 people fit into an 8x8 foot area. Estimate the size of a crowd that is 9 feet deep and 2 miles long on both sides of the street.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

14

step-by-step explanation:

14 x 3 = 42

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
